Louis Pierre Gratiolet (French: [ɡʁasjɔlɛ]; 6 July 1815 – 16 February 1865) was a French anatomist and zoologist who was a native of Sainte-Foy-la-Grande, Gironde. He succeeded Isidore Geoffroy Saint-Hilaire (1805-1861) as professor of zoology to the Faculty of Sciences at the University of Paris.
Gratiolet is remembered for his work in neuroanatomy, physiognomy and physical anthropology. He did extensive research in the field of comparative anatomy, and performed important studies regarding the differences and similarities between human and various primate brains. He is also credited for introducing the demarcation of the brain's cortical surface into five lobes, (frontal lobe, temporal lobe, parietal lobe, occipital lobe and insular cortex).
With Paul Broca (1824-1880) he performed correlative studies of aphasia and the frontal lobe. Gratiolet was a vocal critic of Broca regarding the latter's belief that a larger brain equated to higher intelligence.

Maurice Blondel, a close friend, wrote an obituary account of Delbos and saw various posthumous publications through the press.He wrote on Spinoza, Nicolas Malebranche and Kant. A series of lectures on post-Kantian philosophy, which Delbos viewed as shaped by contingent psychological and social factors rather than through the unfolding of some internal logic, were published posthumously and later (1942) collected in a single volume.Delbos was the father of the violinist and composer Claire Delbos. In turn, he was the father-in-law of Olivier Messiaen.
